A multi-port memory device that prevents degradation of efficiency of a global data drive by turning off the switches, which do not discharge a global data bus. The multi-port memory device includes a global data bus, a banks, each bank including a transmitter and a receiver; ports, each port including a transmitter and a receiver; switches that operate to selectively connect the receivers of the banks and ports to the global data bus; and a switch signal generator for generating a switch signal in response to data drive pulses inputted to the transmitters of the banks and the ports.
